Night lights do not save power while you sleep. 2. We place a smart brightness sensor in the light so that when enough lighting is detected, the night light will not turn on. If you forget to turn off the night light in the morning, no electricity is wasted. 3. Night lights are designed to be superglued to a magnetic base that you can place on a wall, desk, or bed. When you need to go to the bathroom or drink water at night, you can take this lamp with you. 4.
